Accused 'I-35 Rock Thrower' Pat Johnson found guilty in sexual assault trial

Pat Johnson, the man known as the "I-35 serial rock thrower", has been found guilty on indecency of a child by exposure and indecency of a child by contact. The sentencing phase is starting now.

Those counts all tie into a 2013 case involving a teen who says for two years he and Johnson would engage in sexual activity in exchange for drugs and money. The mother of the victim was wiping away tears as Johnson was being lead out of courtroom after he was found guilty.

In June 2016, Johnson was also pegged by police as being the I-35 serial rock thrower. Officers reported responding to nearly 90 incidents of rocks being hurled at moving vehicles from 2014 up until Johnson's arrest this summer. Some of his victims were left with debilitating injuries.

Johnson has been charged in seven attacks thus far.
